RECEPTACLE-GOVER.

SPECIFICATION forming part of Letters Patent No. 794,708, dated J' uly 13, 1905. Application filed February 13, 1905. Serial No. 245,541.

T0 @ZZ whom, it may concer-7c.-

Be it known that I, GUsTAvE D. GLAsER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Receptacle-Covers, (Case No. 1,) of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to covers for receptacles, particularly for such receptacles as bottles or jars.

It has become customary to provide a metallic cover for the mouth of bottles or ars containing preserved or pickled goods or the like, and many forms of such covers have been devised. These covers are usually provided with a washer of wood-pulp, cork, or other soft material and also with a washer of oiled or waxed paper. Locking means are provided for the covers, and the covers Iare usually applied by machinery and under pressure, during which process locking means for the covers are actuated to securely lock the cover over the opening, and the receptacle is hermetically sealed.

Many forms of locking mechanism have been heretofore provided, and one form consists in lugs extending from the edge of the cover, which lugs after application of the cover are bent inwardly to firmly engage below the flange surrounding the mouth of the receptacle to securely clamp the cover in position. When it is desired to remove the and my invention may be considered as an improvement over this form of cover. It is desirable to use the cover for protecting the opening of the receptacle after removal of the cover from clamping engagement therewith; but the lugs, such as described, when bent away from the cover still remain thereon and are continually in the way, besides being very unneat in appearance. These lugs, however, after repeated bending may be broken laway from the cover, but unless special means are provided this breaking away will be very irregular and uneven and the device the uneven and rough edges left after breaking away of the lugs are very sharp and may be dangerous. I therefore provide a special form of clamping-lugs which when bent outwardly from engagement with the flange of the bottle will break away along a predetermined line of decreased strength or crosssection, and the break after removal of the lugs from the cover is regular and removed from any position where harm might result. At the same time the usefulness of the devices as a cover after removal from clamping engavement with the receptacle is not impaired and also presents a very neat appearance.

My invention will be best understood with reference to the accompanying drawings, in which-a Figure 1 is a view of a bottle, showing my improved cover in position thereon. Fig. 2 is an interior view of the cover. Fig. 3 is a sectional view of the cover and part of the bottle, taken on line 3 3 of Fig. l. Fig.4 is a part view of the cover and bottle-opening, showing a modified construction of the lugs; and Fig. 5 is a sectional view on line 5 5 of Fig. 4.

The cover is formed integrally of sheet material, preferably tin, and consists of a shallow cylindrical body portion 1, from the open edge of ,which extend a plurality of lugs 2 2. These lugs may be stamped integrally with the body part and then pressed into shape, as shown, the lugs being normally straight. At the interior of the cover I provide a washer-disk 3, of cork, paper, wood-pulp, or the like, and over this washer I arrange a disk 4, of oiled or waxed paper. After the bottle, such as 5, is filled with goods the cover is placed over the mouth thereof, with the lugs extending straight downwardly beyond the flange 6, surrounding the mouth of the bottle. Pressure is now applied to the cover, and when thus under pressure the lower ends of the lugs are bent inwardly into position below the flange and the cover thus clamped securely in position. The waxed disk and the washer-disk being thus securely clamped over the mouth of the bottle, the bottle is Besides hermetically sealed. When it is desired to roo remove the cover, the lugs are bent outwardly; but to cause the lugs to break away from the body part of the cover upon such outward bending thereof I provide a line or field 7 of weakened strength or cross-section, which may be in various forms. For instance, perforations 8 8, such as shown in Figs. 1 and 3, may be employed, extending transversely across the lugs at some point within the open edge 9 of the cover, and when the lugs are bent outwardly they will bend and eventually break along this line of reduced strength. In the covers heretofore used the lugs were not provided with such predetermined means for determining the line of break, and although the lugs might after successive bendings be` broken away the line of break would be somewhere near the open edge of the cover, and.

generally short stubs would still remain, and

if these stubs after breaking away of the other part of the lug remained turned inwardly it was impossible to apply the cover over the receptacle, and, furthermore, these stubs presented sharp and harmful edges. I therefore, as above stated, place this line of reduced strength at some point within the open edge of the cover, and for this purpose I dispose a slot 10 at each side of the lugs, and at the base of these slots the line of reduced strength extends. Thus when the lugs are bent outwardly the line of break is clear cut land free from extensions, and the cover will always fit over the receptacle. At thefsame vtime the break is removed from the edge of the cover and the user is in no danger of cuts or other injuries. The perforations 8 may be of any shape and of any number.

In Figs. 4 and 5 I have shown another ,manner of providing a line of weakened strength or cross-section, and I have here lshown a channel or groove ll extending transversely across the lugs at the bases thereof. The channel may be cut only on one side of the lug, or the lug may be cut from both sides. The slots 10 10 at the sides of the lugs are here also employed, and when thel lugs are bent outwardly the same results are accomplished as before described.

As many modifications will suggest themselves for causing the breaking away of the lugs along a predetermined line upon removal thereof from the receptacle, I do not wish to be limited to the precise arrangement as p showu. i ters Patent I claim as new and desire to secure by Lettending from said cover for engaging below said flange, said lugs being weakened along a predetermined line, whereby upon removal of said lugs from said flange they will break f away Afrom the cover along said line.

2. The combination with a receptacle havflange to holdthe cover in position on said receptacle, said lugs immediately upon being bent out of engagement with said flange being adapted to be broken away from the cover.

3. The combination with a receptacle having a flange surrounding its mouth, of a cover fittingover the flange, lugs integral with said cover and extending beyond said flange and adapted upon being bent underneath said flange to hold the cover in position on said receptacle, said lugs being adapted to break away from the cover upon being bent outwardly.

4. The combination with a receptacle having a flange surrounding its mouth, of a metallic cover engaging over said flange for closing the mouth of the receptacle, and lugs extending from said cover for engaging under the flange to hold the cover in position on the receptacle, said lugs having a region of reduced strength whereby they will be broken away from the cover upon removal thereof from the flange.

5. The combination with a receptacle having an external flange surrounding its mouth, of a metallic cover for engaging over the mouth, and lugs extending from the open side of said cover adapted u on being bent inwardly to engage below sai flange to hold the cover in position on the receptacle, said lugs having a reduced cross-section at certain places whereby they are broken away from the cover upon being bent out of engagement with the flange.

6. The combination with a receptacle, of a `metallic cover engaging over the mouth thereof, and lugs extending from said cover for clamping said cover into position on said receptacle, said lugs upon unclamping being adapted to be broken away from the cover.

7. The combination with a receptacle, of a metallic cover for closing the mouth or opening thereof, and lugs extending from said cover adapted to be bent to clamp said cover in position on said receptacle, said lugs immediately upon unbending from clamping engagement being adapted to be broken away from the cover.

8. The combination with a receptacle, of a metallic cover for engaging the mouth or opening thereof, and lugs extending from said cover adapted to be bent to retain the cover on said receptacle, there being 'a line of reduced strength extending across each lug, said lugs upon unbending thereof from clam ing engagement being broken away from t e cover along said line of reduced strength.

9. The combination with a receptacle, of a metallic cover for engaging over the mouth tending transversely or opening thereof, and' lugs extending from the open edge of said cover adapted to be bent to clamp the cover into position on said receptacle, therel being an area of reduced cross-section extending transversely across each lug at a point within the o en edge of the cover, unbending of the lugs om clamping engagement causing the lugs to be broken away from the cover along the areas of -reduced cross-section.

10. The combination with a receptacle, of a metallic cover for engaging over the mouth or opening thereof, andlugs extending from the open edge of said cover, there being slots extending inwardly along the sides of the lugs and a line of reduced cross-section exacross each lug at the base of the slots at the sides thereof, said lugs being adapted to be bent inwardly to clamp the cover into position on said receptacle, and unbending of the lugs from clamp- ,ing engagement causing said lugs to be broken away from the cover along said lines of reduced cross-section.

11. A metallic cover for en aging over the mouth of a bottle or receptac e consisting of a cylindrical body portion, and lugs extending from the body portion to be bent to form clamping engagement lwith the receptacle when applied thereto, said lugs being provided with means for causing breaking away thereof from the cover upon unbending thereof from clamping engagement.

12. A metallic cover for engaging over the mouth of a bottle or other receptacle which consists of a cylindrical cap portion, and lugs extending from the open edge thereof and adapted upon being bent to form clamping engagement with the receptacle to retain the cover thereon, there being a line of weakened cross-section extending across each lug at the base thereof, whereby upon unbending of the lugs from clamping engagement said lugs are broken away from the cap portion along said lines of reduced cross-section.

13. A metallic cover for engagement over the mouth of a bottle or other receptacle consisting of a cap portion 1, and lugs 2 extending from the open edge thereofv and formed integral therewith, there being a region 7 of reduced cross-section extending across the lugs at the bases thereof.

14. A metallic cover for engagin over the mouth of bottles or other receptac es which consists of a cap portion l, and lugs 2 extending from the open edge thereof and formed integral therewith, there being 'slots 10 cut through the cap portion at the sides of the lugs, and a line 7 of reduced cross-section extending transversely across each lug at the base of said slots.

In witness whereof l hereunto subscribe my name this 9th day of February, A. D.
